Toyota / Lexus DTC delete. Load the ECU dump, pick the ECU type, type the DTC code (e.g. P0171) in the box, then CHECK to confirm it is present or DISABLE to zero it and save the file. It confirms whether the code was found and disabled. You can type several codes (space/comma separated). DENSO auto-detects GEN1/GEN3; Delphi is a separate set. Flash: fix the checksum in your programmer before writing. Always keep a backup of the original read.
